STATION KEEPING METHODS

Abstract:

A method for maintaining a marine vessel at a target position in a body of water, the method being carried out by a processing system and including: estimating at least one roughness condition of the body of water based on measurements related to an attitude of the marine vessel; calculating a desired linear velocity based on a difference between an actual position of the marine vessel and the target position; filtering an actual linear velocity of the marine vessel based on the roughness conditions; and operating a propulsion system of the marine vessel to move the marine vessel to minimize a difference between the desired linear velocity and the filtered actual linear velocity. A method for maintaining a marine vessel at a target heading in a body of water is also disclosed.
